Wave Solder Process Considerations &
Set-up for Lead Free
Wave soldering with lead-free materials is probably the most demanding of the changes to traditional assembly methods due to the higher temperatures associated with the solder. In air there is likely to be an increase in dross production and with the higher tin content the cost of running the machine will be higher. To date most of the research experience in wave soldering with lead-free materials has been using nitrogen inerting. Most of this authors trials and much of the Japanese industry has been in air.

VIA's New PT Chipsets Today VIA is announcing their new PT series of chipsets to the masses. The chipsets that make up the PT series represent the first real alternatives to Intel�s chipsets for the Pentium 4 platform and aim to ease the transition to PCI-Express and DDR-II.
BEST Instructors have put to video demonstrations of common hand soldering skills. These are not designed to be in place of live one on one training where repetitive skills and subsequent one on one feedback is given. Rather they are quick refreshers designed to be viewed if a specific skill has not been practiced in a while.
Restructuring Rework Process - Back to Basic
In general, I am looking at restructuring of our rework processes in our factory. Despite all the effort put into design, process, material etc, there will always be some assemblies that must be repaired...
